RACK roa BOTTLE-CLEANSINGMACHINES.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application filed August a, 1912. Serial No. 713,071..

To ail whom iii may concern:

Be it known that I, ALFREn HANNAFORD,

- a citizen of the United States, residing at scribed in United States Letters Patent. No.

1,012,843, granted to Sigmund L. Goldman, December 26, 1911;. and it relates, particularly, to an improvement in the construc- 'tion of the gate-operating means,.the object being to cause the gate-forming bar, by shifting it lengthwise, alternately in opposite directions, from one locked position to another, to move by gravity to its-respective rack opening and closing positions, thereby greatly to, simplify the construction.

In the accompanying drawings, Figure 1.

shows the rack provided with my improve ment by a broken view in elevation, the View presenting, in a diagrammatic way, stationary cams interposed in the paths of the opposite ends of the gate for shifting it lengthwise respectively in opposite directions; Fig. 2 is an enlarged sectional view of one end-portion of the gate in its guiding-loop, and Fig. 3 is a similar view 'show-. ing the opposite end-portion of the same; Fig. 4 is a section through the rack on line 4, Fig. 1, showing the angle of inclination at which it is carried vertically through the tank of the machine; Fig. 5 is a View of the rack like that represented in Fig. 4, but showing it extending in the reverse direction, or that in which it extends whenon the opposite side of the machine; Fig. 6 is a broken face-view of one of the'rack-heads showing the gate-guiding loop thereon, and Fig. 7 is an end view of the rack-head shown in Fig. 6, as regarded in the direction of the arrow on the line 7 in that figure.

The rack 8 shown is of the same construction, as to its body-portion, as that illus-- trated and described in said patent, and

comprising the perforate sides 9, end-heads 10 having reinforced ears 11 projecting from their outer faces to beriveted to endless chains, indicated at 12' in Fig. 1, forming the vertically traveling conveyer in the tank 12 of the machine, and perforate partitions 13 extending at intervals between the sides to form pockets. a

I plained,

On corresponding ends of the heads 10 are provided (being preferably cast thereon for guiding and locking the gate 1 1, as hereinafter described) similar loops 15, each forming an arc-shaped slot or passage 16;

terminating in end-sockets 17 and 18,greater in diameter than the width of the slot and each having its wall elongated or extended outwardly as shown at 19to increase its bearing surface. The-sockets 18 aline with each other and are each midway between the lateral edges of 'a' head 10; and the' sockets 17, which also'aline, extend beyond corresponding corners of the opposite heads. The gate 14 is a bar, preferably formed of a section of metal pipe, with similar solid stems 20 and 21 secured in its opposite ends to extend-therefrom. Each stem is formed with a circumferentially-reduced intermediate section 22 of a diameter adapting it to traverse a loop-slot 16, the greater diameter of the stem-sections at opposite sides of the section 22 adapting them to fit in the sockets'17 and 18, butv preventing their entrance into the slots; and

these stems'terminate at their outer ends in similar heads 23 and 24, shown of tapering form. In Fig. 3, the stem 21is shown to be somewhat'reduced in diameter between the head 24 and section 22 to form a beveled section 25 for the purpose hereinafter ,ex-

In'use, the rack is one of a series of racks extending, at proper intervals, between the conveyer-forming chains, in a tank 12, and to which the'racks are fastened by riveting through their ears 11.

Following, now, one rack through the tank: .115 represented in Fig. 1, the gate 14 rests at "the larger sect-ions of itsstems or end-portions in opposite sockets 18 of the guides 15, thus in its open position, being locked to permitthe empty rack. to be filled with bottles, the rack being on the rear or filling side of the machine, with a. cam 26 projecting from a wall of. the tank into the path of the gate-head 23. In the downward travel of the rack the head 23 encounters the cam 26, whereby the gate is shifted length-- wise in its bearings 17 to bring its reduced sections 22 into registration with the corresponding ends of the loop-passages 16, through; which said sections pass by the gravity of the gate, causing it to drop into the then extending the gate centrally along its month.

lower sockets 18, there to close the rack by This after the rack has been filled with hottles. Thereupon in the continued travel of the rack on the same side of the machine, the then projecting head 24'encou-nters another or second cam (not shown, but like the cam 26)projecting-int0'its path from the wall of the tank opposite that from which the cam 26 projects. By this encounter the gate, in its closed position, is shifted lengthwise in the sockets or bearings 18 to, remove the sec tions 22'out of registration with the slots 16 and bring the larger sections of the gateends into such registration, thereby locking the gate in its rack-closing position, in the. sense of obstructing it against movement through the slots 16 from the socket bearings confining it. Thus the head 23 is again pro-, 'truded as represented in. Fig. 1, from a then lowermost socket 18.- In-the continued travel of the rack it attains and moves upwardly along the discharging side of the machine, on which there projects from a wall ofthe tank into the path'of the'head 23 a. third cam (not shown, though like but inverted relative to the cam 26). Bythis encounter the. gate is shifted lengthwise in its then uppermost bearings 18 to register the reduced end-sections 22 with the adjacent ends o-fihe slots 16, through which they pass by the gravity of the gate, which drops into the sockets 17, thus opening the rack to permit' the bottles to discharge from it automatically. by reason of its downward inclination toward .the rack-mouth. .The discharge may take place, as usual, upon a suitable chute v( not shown) in proper position to receive it.

In the continued upward travel of the rack, the then rotrudin "cam 27, like'the a oresaid third cam, projectingjnto the pathof that head from a wall of the tank opposite the wall thereof from which such third cam rojects; and by thisencounter the 'ate is shifted lengthwise to lock it in its rack-opening position in the sockets 17, in thesaine way and sense hereinbefore'described of its being locked in the rack-closing positions in the sockets 18.

. When, therefore, in the continued travel of the rack, with its gate open and locked, it again attains the filling-side of the machine, repetition of theoperations thus described will ensue.- I

In the locked positions of the gate, its weight retains it in place in the bearings againstt-he tendency of jarring to shift it longitudinally; but this tendency is further resisted by the beveled sect-ion 25 of the stem 21 in presenting an inclined surface against riding intothe bearing-socket17- or 18 then adjacent to it.

As will be understood end-portions lengthwiseshiftingly in bearings on the opposite ends of the rack for the head 24 encounters a from the foregoin description the gist of my improvement lid; in supporting the gate-forming bar at its" open and closed positions of the gate, the

bearings for each gate-end being connected by'aguide-passage for movement of the gate by gravity from one position to the other when shifted in one direction, but the gate becoming locked in its bearings against-such movement when shifted in the opposite direction. It is 'tobe realized, therefore, that considerable variation is; possible in the details of construction herein shown and described, and I do not intend by illustrating a single specific or preferred embodiment of my invention to be limited thereto; my inclaim protection upon all the novelty there maybe in my invention as broadly as the state ofthe art will permit.

VVha-t I claim as new and desire to secure by Letters Patent is 1. In combination with a bottle-rack body, a gate-forming bar, bearings on each end of said body for the end-portions of said bar in the open and closed-positions of the' gate, in which bearings said bar is lengthwise-shiftingly supported, the bearings for each of said end-portions being connected by a guide-passage for movement of the gate from one position to theother when shitted in one direction,and means locking said end-portions in their bearings against said movement of said bar when Shifted in the. opposite direction.

2.'In combination .with a bottle-rack body, a gate-forming bar provided with endheads, bearings on each end of said body for the end-portions of said bar 1n tention being in the following claims to the open and closed positions of the gate, in a which bearings said bar is lengthwiseshiftingly supported, the bearings for each of 'saidend-portions being connected by a passages when the gate is shifted in one direction, and relatively-large sections seating in said sockets and locking therein the gate when shifted in the opposite direction.

4. In combination with a bottle-rack body, loops on the ends of the body, each forming relatively-large end-sockets and a relatively-narrow arc-shaped slot connecting them, and a gate-forming bar supported at its end-portions lengthwise-shiftingly Lowes having relatively-small sections to registerwith and traverse said slots when said bar shifted in one direction, and relatively-f large sections seating in said sockets and locking therein the gate when shifted in the v shifted lengthwise and movable by gravity 5.
